For this list, we picked products based on actual customer reviews and ratings on Amazon, Bunnings and eBay. For every category, we carefully chose parameters based on our research and determined products with the highest review score within those parameters.
With a rating of 4.5 out of 5 stars on Amazon, we recommend Roundup's Naturals Glyphosate-Free Powerful Weed Killer as the best natural/organic weed killer.
This Roundup natural herbicide is made of 100% natural active ingredients to bring visible results in just an hour. It is free of glyphosate and remains effective within 3 hours even when it rains. According to the company, it completely kills weeds in 24 hours, allowing you to replant or reseed right after.
This natural weed killer comes premixed with a pressure spray, making it convenient for spraying gardens, pathways and other areas. Customers loved its fast-acting formula that effectively gets rid of most unwanted weeds. It also doesn't leave any residue in the soil. However, several customers said that its sprayer is hard to use. Others also mentioned that they needed multiple coatings to kill stubborn weeds, but this seems to be an isolated issue.
Yates' Ready to Use Zero Rapid 1 Hour Action Weed Killer is a non-selective, all-purpose weed killer that effectively gets rid of different weeds within an hour. According to the manufacturer, it is rainproof after 30 minutes and is non-residual – you can plant on the sprayed area after 7 days.
Customers gave positive feedback on the product's convenience, fast action and versatility. It produces visible results within an hour, but since it's a non-selective herbicide, it will kill everything it touches. Reviewers also loved that it's safe for pets and children once dried. However, there were complaints about the trigger being difficult to use. A few others also mentioned that a single bottle isn't enough to cover larger areas, but this seems to be a minor concern.
For the best selective option, we recommend Nufarm's Kamba M Selective Herbicide. At Bunnings, it has a rating of 4.9 out of 5 stars.
Nufarm's Kamba M Selective Herbicide is a 5L weed killer that can treat up to 7,500sqm of turf. It can control a variety of weeds, including bindii, clover, capeweed and thistles. It's a glyphosate-free solution with dicamba as an active ingredient.
Reviews said that it effectively kills weeds after just a day. A few others also added that it gets rid of flat weeds and broadleaf weeds, leaving their lawn luscious and healthy. One 5L jug is also enough to cover larger areas, according to customers. However, the company mentioned that it's not suitable for buffalo turf.
When it comes to non-selective herbicides, we chose Roundup's Fast Spray Ready Weedkiller as the best option. It has a rating of 4.8 out of 5 stars at Bunnings.
Roundup's Fast Spray Ready Weedkiller is a non-selective herbicide that can tackle all your weed problems within an hour. The ready-to-use formula works on most weeds and grasses, with a 5L bottle covering up to 75sqm.
The general sentiment is that this herbicide is a powerful, fast-acting weed killer for controlling anything in your garden or pathway. One reviewer added that it controlled the weeds on their pebbled driveway without damaging the pebbles. It comes in child-resistant packaging for better security as well. Several customers wish it came with its own sprayer but added that it's not really a huge issue.
Garden Basics' Ready to Use Weed Kill is our pick for the best cheap weed killer available online. It has a rating of 5 out of 5 stars on Bunnings.
Garden Basics' Ready to Use Weed Kill is a non-selective herbicide that controls foliage and roots. It comes in a ready-to-use trigger spray bottle, allowing you to spot-weed. It is also non-residual, which means you can plant in the sprayed area after several days.
Since it contains glyphosate, this herbicide will kill anything it comes into contact with. Customers loved using it for weeding their gardens and paths. Others also mentioned that it works just as well as other pricier options. However, it has a strong chemical scent that may be off-putting. Additionally, a single 1.2L bottle isn't enough for larger areas.
For garden beds, we recommend Yates' Ready to Use Nature's Way Organic Weed Killer Spray as the best weed killer. It has a rating of 4.7 out of 5 stars on Bunnings.
Australian Certified Organic and approved for organic gardening, Yates' Ready to Use Nature's Way Organic Weed Killer Spray is a glyphosate-free, non-selective herbicide that controls a wide range of garden weeds. It can kill dandelions, clover, broadleaf weeds, algae and moss. It is non-residual, allowing you to replant after 7 days of spraying.
Customers gave positive feedback on the product's organic formula, fast action and ease of use. This herbicide is clove-oil based, which controls some weeds within an hour. At a little under $25, it's quite an economical option for garden beds, rockeries and driveways. However, it's not rainproof; the company advises not using the product if rain is likely within 2 hours.
With a rating of 5 out of 5 stars on Bunnings, we picked Roundup's Herbicide Liquid Concentrate Weedkiller as the best weed killer for large areas.
Roundup's Herbicide Liquid Concentrate Weedkiller is a powerful water-soluble herbicide that controls annual and perennial weeds, such as chickweed, sow thistle, blackberry and bamboo. A 5-litre bottle can cover up to 1,000sqm or an area up to the size of 4 tennis courts. It comes in child-resistant packaging and is non-residual.
Roundup is Australia's best-rated weed killer brand, gaining the highest marks when it comes to ease of use, effectiveness and value for money. The brand's Herbicide Liquid Concentrate Weedkiller quickly kills weeds thanks to its powerful non-selective formula. It also doesn't remain active in the soil, allowing you to plant after just 7 days. However, we recommend taking extra precautions when using this herbicide as its strong concentration may cause some skin irritations.
For the best pet-friendly option, we picked Natural Armor's 30% Vinegar Pure Natural & Safe Industrial Strength Concentrate. It has a rating of 4.5 out of 5 stars on Amazon.
About 6 times stronger than vinegar, Natural Armor's 30% Vinegar Pure Natural & Safe Industrial Strength Concentrate is a natural herbicide that can also be used as a deodoriser and surface cleaner. It is environmentally friendly and safe for use around pets.
This non-selective weed killer effectively kills overgrown and stubborn weeds in gardens, patios and other large areas. Because it has a potent 30% vinegar formula, reviewers recommended wearing protective gear before usage to avoid any irritation. Customers also loved using this product to keep their households sparkling clean. At over $180 for a gallon, it's more expensive than traditional weed killers. However, customers said that its eco-friendliness, versatility and potency are well worth it.
Roundup's Tough Ready to Use Pump 'N Go Weedkiller is our choice for the best weed killer for grass. It has a rating of 4 out of 5 stars at Bunnings.
Roundup's Tough Ready to Use Pump 'N Go Weedkiller is a premixed herbicide that effectively kills weeds and grasses – roots and all. It comes with a Pump n Go pressurised spray for easier usage. According to the company, it is rainproof after 30 minutes and is non-residual. After 7 days, you can safely replant or reseed in the sprayed area.
Customers praised the product for being convenient and fast-acting. The premixed formula is suitable for people with busy schedules. The included spray head has 2 spray patterns: foaming action and drip guard, allowing you to evenly coat those pesky weeds. This non-selective herbicide is suitable for onion weed, blackberry, English ivy and other grasses. However, some customers said it's not strong enough for their liking. Others also said the spray is quite difficult to use, but this seems to be a minor issue for most buyers.
Surefire's Buffalo Bindi & Broadleaf Weedkiller is our pick for the best weed killer for buffalo grass. On eBay, it has a rating of 5 out of 5 stars.
Surefire's Buffalo Bindi & Broadleaf Weedkiller is a concentrated herbicide formulated with bromoxynil and MCPA. Bromoxynil is a nitrile herbicide used for post-emergent control of annual broadleaf weeds, while MCPA is a phenoxy herbicide used for perennial weeds. This powerful solution also effectively gets rid of stubborn weeds on buffalo, kikuyu, couch, Queensland and blue couch grasses.
The general sentiment is that this weed killer is a potent product that easily kills various weeds in different grass types. Customers said it's especially effective for buffalo and kikuyu grasses, leaving their turfs luscious and healthy sans weeds. It's a concentrated formula that needs to be mixed with water, which may be a con if you're new to herbicides or lead a busy lifestyle.

Amgrow's Multiweed All-Purpose Weeder is a selective herbicide used to kill oxalis, bindii, dandelion, flat weeds and many more. It is suitable for most lawn types, including blue couch, carpet, Kentucky bluegrass and ryegrass. However, it's unsuitable for buffalo lawns.
Despite its small size, this concentrated formula can cover up to 125sqm. Additionally, you only need about 20ml mixed in 6 litres of water for a 10sqm area. Customers said that it quickly kills stubborn weeds and grasses. But despite being a selective solution, one review said it still impacts nearby plants. To avoid this issue, we recommend using a more effective selective herbicide instead.

A weed is a plant that grows somewhere it isn't wanted. Weeds offer no value at all to your lawn, and they steal water and other nutrients from your lawn and plants.
Many weeds also spread easily and can be quite invasive, ruining the look of your otherwise well-manicured lawn. Common weeds in Australia include clover, dandelion and the dreaded bindii.
Weed killers are herbicides that use chemicals to attack and kill weeds. However, the way they work, and the parts of the plant they target, can vary from one product to the next.
Before you can start shopping for a weed killer, it's important to understand that weed killers work in different ways. As a result, the right product for you will depend on the weed problem you need to tackle.
Pre-emergent weed killers stop weeds from germinating, while post-emergent products kill weeds once they appear through your soil. You can also differentiate between weed killers based on their method of operation:
Weed killers can also be selective or non-selective:
You'll need to consider several factors when deciding on the right weed killer for your needs.
Are you targeting seasonal weeds or weeds that are a problem all year round? Are you trying to kill off an entire section of weeds or "spot kill" specific plants around your lawn? Do you just want to target the parts of the weed that are above the ground or kill off the entire plant?
Once you've answered these questions, you can narrow your choice down to a contact, systemic or residual weed killer and decide whether you want a selective or non-selective product.
Check what you need to do to use the weed killer in your yard. Some products come in their own ready-to-use spray bottle, while others are sold as a concentrate that you can dilute into a spray bottle with a weed wand.
Selective herbicides are also available in spray bottles you can attach directly to your hose or as granular products that can be sprinkled on your lawn.
It's worth noting that many broadleaf weed killers will also affect buffalo grass, so check the label to find out whether a product is safe for use on your lawn. Also be sure to check whether a product is designed for lawn use or whether it's a residual weed killer designed to be used on paths and pavers.
Check the label for a guide to the number of weeds you can expect to kill with one bottle or the maximum yard size a product is designed to cover.
If you're concerned about the safety of a particular product, check the label to find out what active ingredients it contains. One of the most common ingredients is glyphosate, a non-selective and systemic herbicide.
Selective weed killers will often also include fertiliser. This means they can be sprayed onto your lawn to kill the weeds you're targeting and also provide nourishment for your lawn at the same time.
Prices vary depending on the type of weed killer you buy and how it is packaged. The price of 1L of weed killer concentrate ranges from approximately $7 to $30, while 750mL ready-to-spray bottles range from around $7 to $15.
When comparing two similar weed killers, remember to compare the price per 100mL to ensure a fair comparison.
While you can overcome weed problems with weed killers, prevention is always better than a cure. There are plenty of simple things you can do to minimise the weeds in your lawn without having to reach for the chemicals:
There are a few other factors you should consider before buying weed killer:
